Embodiment Construction

[0027] The present invention will be further elaborated and described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention cannot be limited by this.

[0028] see figure 1 , figure 1 It is a schematic structural diagram of the reaming tool for a low-speed marine diesel engine of the present invention. As shown in the figure, a reaming tool for a low-speed marine diesel engine includes: a beam plate 1 with a waist-shaped hole, a first backing plate 2, and a full-threaded bolt 3 , guide rod 5, reaming broach 6, screw jack 7, hex nut 8 and oil cylinder 9 connected with hydraulic pump by oil pipe.

[0029] The bottoms of the two ends of the beam plate are respectively fixed with the top of the oil cylinder and the top of the screw jack, and the level of the beam plate is kept, and one end of the fully threaded bolt passes through the waist-shaped hole of the second backing plate 10 and the beam plate and the beam. ...

Abstract

The invention relates to a reaming fixture and method of a marine low speed diesel engine. The reaming fixture comprises a cross beam plate with a waist-shaped hole, first base plates, a screw bolt, a guiding rod, a broaching cutter for reaming, a screw jack, a hexagon nut and an oil cylinder, wherein the oil cylinder is connected with a hydraulic pump through an oil pipe; the top parts of the oil cylinder and the screw jack are respectively fixed below the two ends of the cross beam plate; the cross beam plate is kept horizontal; and one end of the screw bolt penetrates through the waist-shaped hole of the cross beam plate, and the other end of the screw bolt is fastened with a workpiece to be machined through the hexagon nut and the first base plates. A cylinder block and a rack on a station or connecting bolt holes in the rack and a machine seat are stranded and corrected without affecting the assembly work of other mainframes, thus the reaming method is convenient, the overall effect is greatly improved, and the mainframes are guaranteed to be smoothly folded.

Description

technical field [0001] The invention relates to the technical field of marine low-speed diesel engine processing, in particular to a reaming tool for a low-speed marine diesel engine and a method thereof. The method of strand correction. Background technique [0002] The base, frame, and cylinder block of marine low-speed diesel engines are all segmented, and after the processing of each segment, they are assembled and installed in the assembly workshop. Therefore, the smooth progress of closing is directly related to the overall quality of the host. In the closing stage, the process requires guide pins to penetrate the tight fitting bolt holes at the four corners of the cylinder block, frame or machine base for on-site positioning, and then penetrate the bolts on the connection surface for fastening. However, in the actual assembly process, sometimes due to deviations in the machined holes on the connecting surfaces of the machine base, frame, and cylinder block, after th...
